Need NUC advice (migrating from Pi3B

With over 60 zwave devices, >10 media players and about 30 other IP based integrations my PI3 is getting a bit slow.

So I’m looking to migrate to something faster.

  • Want to keep using HASS.IO
  • I want to run a dedicated HASS server, so no other stuff beside some hass.io add-ons
  • Unifi controller and Caddy server are both on a dedicated PI (and want to keep it like that)
  • Plex & BlueIris (7 cameras) now run on a Win10 Machine which also doubles down as NAS (and want to keep like that for now)
  • I have a UPS which I will connect the NUC to (also now holds all other above mentioned hardware)

NUC’s come in many sizes/prices. What would be an appropriate choice given above?

I just did this upgrade a few weeks ago and went with a i5 gen 7 and I run it as you say for running hassio in docker with Ubuntu server. This is massive overkill and you could easily run it off a pentium version. I had gone with the i5 as I was always going to be doing ml and facial regonition with this machine and wanted the extra grunt.

Thanks. Did you see significant improvements? I was also lookin into facial recognition. Is that easy to do with Blue Iris on another machine?

Which type did you get? Seems that some do not restart after power failure. That would be killing

I am running HA on a 5 year old i5 nuc + ssd in a docker container with over a hundred devices (no zwave, all Zigbee and wifi).

I performed a little 3 minute test with 4 ui’s and it tried to hit HA as hard as possible. Although the HA ui lovelace keep responsive, I noticed that HA used quite some CPU, as you can see below:

The memory 16GB memory is over kill. It does not use more than 1 GB. I think a current generation i3 is more than enough.

How are you getting greater than 100% CPU utilisation?

Well, not really. Seldomly goes over 80%. But I’m also recently had a corrupted SD card and people that have moved to a NUC have reported dramatic speed increases. If it does not work out I’ll plan to use the NUC as my BlueIris & Plex server. This is now stil on and old PC consuming >90 watts .

I have about 30 ddvices mostly wifi and the traccar zerver and cctv server and nerver come over 30% cpu . The cctv has 7 cameras

Using an inexpensive USB to SATA adapter + SSD instead of an SD card will give you a good performance boost and is rock solid reliable.

Thanks. Would this require extra power to the PI? I’m asking as I now use a POE to Pi converter (delivering 2A max). I guess you loose the advantage of easily swapping SD cards if something else goes wrong (eg revert quickly to previous version)

That poweradapter can be a problem. Pi should 2.5 to be sure

`sorry, it’s actually 2.4A

My i5 core has 4 cores. cpu utilization of a Linux process is the amount of cpu time used. The Linux kernel calculates cpu utilization based on the number of time slices per process. A docker container is just an isolated process. If you don’t put a quota (limit) on a container, then it theoretically could consume all host cpu time.

I am powering my pi with only a 2.1amp power supply (old iPad charger) and this setup has worked perfectly for me for over 15 months. I made the jump to SSD primarily because I experienced two prior SD card corruptions and was about to give up on the pi but had a spare ssd so figured what did I have to lose but $8.00 for the adapter. I use the SD card as a cloned backup now, but have never had to use it since the SSD is 100% reliable.

Did you also get a speed improvement? I experience a somewhat slow zwave network response & logbook/history are practically not usable (even with purge each 7 days)

When I had a Pi the main slowing seemed to come from limited memory and CPU.

For my use case (Wired ethernet, Z-Wave using Aeotec USB, Mochad (X-10), Sonos, Envisalink Alarm integration, 7 day log purge, booted on SSD, off the top of my head at least 2-3X as fast as the SD card was (caveats–going off my memory here, HASS itself is faster than it was a year ago). I would say the performance increase was similar to going from hard-drive to SSD on a desktop computer.

Case in point, just checked and it takes <7 seconds to pull up full (7-day) activity Logbook (~3500 log entries) and < 2 seconds to pull up the History pane for same period.

Client computer is Macbook 2018 13" (4-core), Chrome browser.

My Z-wave is essentially, instant. I did use a 12 foot USB extender cable to mount the Aeotec USB on the ceiling of my basement–that definitely helped Z-wave range/speed.

Well, logbook & history now even crash HASS completely (wanted to also time it knowing t would take more then few mins). DB is working fine as I get a history card on a device.

What do you see with “Free” command in terminal? I have almost 400mb of unused memory. Oh and I’m running pihole on this pi as well.

Size of .db is 2gig. memory & CPU below

Your mem and cpu utilization look fine. IMHO, you would almost certainly benefit heavily from an SSD vs SD card. FYI-My db is only about 1gb, about half of yours, with a 7-day retention period–even then, I am logging a bunch of activity that I don’t care about–I think I will exclude more activity than what I’m currently logging!

Note: I’m running regular 'ole HASS in a venv, not HASS.IO
